Abstract

The femur component for a hip endoprosthesis has a distal end (1) intended to be introduced into the femur's (19) medullary space (18), a proximal collar section (2) with a neck (3) to which a ball head can be fastened, a shaft section (4) between the collar section (2) and the end (1), with a longitudinal axis (5) and length L, an anterior side surface (12), a posterior side surface (13), a medial side (14), and a lateral side (15). A pocket-shaped recess (6) is provided on the anterior and/or posterior side surface (12, 13), lying in the proximal third of the shaft section (4) that blends into the collar section (2). The anterior and posterior side surfaces (12, 13) and the medial side (14) converge conically towards the end (1). The femur component according to the invention enables a good positive-locking fit, with proximal anchoring and primary stability, to be achieved.

Trochanteric implant for forming femoral prosthesis, has hooks that allow fixation of femoral tuberosity part on implant by using encircling devices and with pin and throat respectively, where one of hooks enclose encircling devices
